Title: Optical system for projection type picture display device
Inventor: YOSHIDA TAKAHIKO
IPC: G02B13/16
Filed: 1989-06-16
Abstract: PURPOSE:To decrease a drift attended with a temperature change in convergence correction and to attain high picture quality by arranging a concaved meniscus lens to a position closest to a cathode ray tube side in each projection lens group, sealing a transparent liquid refrigerant between the cathode ray tube and the lens and providing a heat pipe. CONSTITUTION:A concaved meniscus lens having a concaved face to a transmission screen 10 side is arranged to a lens closest to cathode ray tubes 2R, 2G, 2B side among the lens group forming projection lenses 3R, 3G, 3B. Moreover, a transparent liquid refrigerant is sealed in couplers 4R, 4G, 4B and heat pipes 11-1, 11-2 are inserted above and under the transparent liquid coolant in the couplers and arranged. Thus, a heat caused in the cathode ray tubes is transmitted to the transparent liquid refrigerant and the heat pipes and when the heat reaches an equilibrium, the red, green and blue transparent liquid coolant reaches nearly the same temperature. Thus, a drift attended with the temperature change of convergence correction of the optical system for the projection picture display device is reduced while obtaining an excellent focus.

Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To simultaneously produce images having a plurality of viewpoints by disposing an optical element for changing the advancing direction of a light in the full surface or the back surface of each pixel constituting a spatial optical modulation element. SOLUTION: Fresnel lens 14 is disposed in front of light sources 12A to 12C and the image of a light emitted from each of the light is formed in the vicinity of the viewpoint position of an observer positioned in the front side. A light emission controller 13 causes the first to the third light sources 12A to 12C to emit lights in sequence. An image selector 18 selects, each time a light source number 17 currently emitting a light is inputted, two from six parallax images supplied from a six lens camera 11 based on this light source number 17. A LCD 15 displays a parallax image corresponding to a lighting light source among a plurality of light sources. Further, the light of the first light source 12A is divided by a prism 16 and two real images 21A and 21B are formed in the left and right sides of the real image positions of the first light source 12A having no prism 16.

IPC: H04N1/32
Filed: 1995-05-26
Abstract: PURPOSE: To provide an NCU, with which communication is possible in the state of impressing no direct current(DC) while preventing a circuit from being complicated, concerning the NCU provided with a DC loop forming circuit for forming a DC loop while using a semiconductor element such as a transistor to be operated by impressing a voltage from a line. CONSTITUTION: Since any element requiring DC impression is not provided at a signal transmission path and a diode bridge 107 is inserted only to the path of DC loop formation, an input/output signal is transmitted to a facsimile transmission/reception part 108 without being passed through the diode bridge 107. Therefore, the signal can be transmitted/received regardlessly of whether the DC is impressed or not.

Title: Camera picture background mask system
Inventor: SAITO AKIRA
IPC: G03B15/08
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To accurately extract only an object by simple constitution. SOLUTION: The outputs of an infrared CCD camera 4 and a CCD camera 5 are inputted to a picture processing part 6 and temporarily stored in a buffer part 8. By the processing part 6, a picture formed by infrared rays is read out from the buffer part 8 and the inputted picture is binarized with the previously set level of binarization with a reference by a binarization processing part 6a (1 and 0). Since the infrared rays reflected on the part of the object becomes larger than the set level, it becomes '1' and the other background part becomes '0'. Thus, the picture formed by the infrared rays is binarized so as to make a mask. Besides, a picture formed by visible light beams and the mask are synthesized by a synthesis part 6b and the picture obtained by extracting only the object is formed.
